[rlug] Pin package pe debian

[Paul Lacatus (Personal)]

Vreau sa instalez RabbitMQ pe un raspberry pi.  Pachetul de RabbitMQ are 
ca dependinta erlang dar  versiune >1.19 . In main e erlang 1.19.2.  Am 
pus in /etc/apt/preferences.d fisierul cu preferinte pentru erlang :

# /etc/apt/preferences.d/erlang
Package: erlang*
Pin: release o=Bintray
Pin-Priority: 1000

dar desi am dat nenumarate apt-get update la apt install erlang-nox imi 
pune tot 1.19.2 din main

nu tine cont de fisierul de preferinte, la apt-cache policy :

root at raspi_rabbit:/etc/apt/preferences.d# apt-cache policy
